the diagonal is the side times \(\sqrt2\) \that means \[x\times \sqrt2=12\] making \[x=\frac{12}{\sqrt2}\]

to get the radical out of the denominator in \(\frac{12}{\sqrt2}\) multiply by \(\frac{\sqrt2}{\sqrt2}\) i.e. \[\frac{12}{\sqrt2}\times \frac{\sqrt2}{\sqrt2}\]

you get \[\frac{12\sqrt2}{2}\] then reduce the fraction
